24 Range Motors (Skeletal Frame)

24 Range Electric Motors - Shaded Pole, Skeletal Frame

The simplest of all motor types, they consist of two basic electrical assemblies: a single bobbin wound stator and a die cast rotor assembly. The auxiliary winding of the motor is provided by two coils of thick copper wire looped around each pole face.

These shading coils remain in circuit whilst the motor is running and oppose the main winding flux, resulting in lower motor efficiency.

Starting torque of this type of motor is influenced by the diameter of the shading coil. Higher start torque usually means lower running performance, and final design is usually a compromise between these two parameters.

Applications

General 24 Range motor specification only. Refer to individual models or Sales Office for particular details and further information if required.

The performance characteristics of skeleton motors dictate that they are generally used for air movement or liquid stirring duties. Their simple compact construction, quiet operation and low cost make them ideally suited for these applications
